I'm only really worried about the low pressure codes...
Anybody have experience with this????
The CEL came on (after the code was thrown) after I wailed on it at WOT 1-3 gears. Odd...

for the fuel pressure issues i would try replacing the fuel pressure switch, my cousin had similar codes and replacing the switch did the trick

Either that or the fuel supply pump.
Seems like it happened at very high rpm and engine load so could very well be that the pump is wearing out and can't keep up in extreme situations when fuel demand is very high.

Fuel filter

This seems like the best thing to try first http://****************.com/smile/emthup.gif

I appreciate the suggestions guys...Honestly.
But has anybody actually seen these codes first-hand and applied one of these solutions? I really hate throwing crap and hoping it sticks. I guess I'll have to do it, but would like a few more first-hand experienced guys to chime in before I do so.
Hope you guys understand, and I do appreciate the help...just want to make sure I'm not wasting time here.
I used vag-com to run some output tests on the motor and seems everything checks out. Figures.

Re: FV-QR (nater)

There was a guy in the 3.6 tech sub-forum with similar codes a month or so ago. He replaced the pump if I remember it right. Fuel filter would be the cheapest and easiest check though and replacing it might not be a bad thing even if that doesn't cure the problem.
Also have you tried to reset the codes and gone for another high rpm/high load test drive to see if they come back?

I'd rather not reset the codes...the CEL went off and it'll usually keep time-stamps of wheni t occurs again. Reason I don't want to reset is I will probably get this done under my extended warranty, and am worried the code WON'T come back. Hoping the dealer will throw some stuff at it since it's not THEIR warranty that's paying. Not saying they should...just saying that they may be "less-cheap" and more willing to get it done for me since I'm at 87k and warranty out at 100k.
Thanks all. I'll report back...

Re: FV-QR (nater)

Hi,
Exactly the same errors I had in my cars. I waste 3 month in the vw dealer service.
Were changed regulator of low pressure pump, high pressure pump (common rail), updated programs.
But problem was a low pressure pump fuel tank. I was very disappointed whit the vw service
